Here are all the models currently in the database for this WD drive family (Caviar Green/GP). Entries are sorted into sections based on platter density.

Some tips:

Drives using odd sizes are sorted into whatever size category that's closest. For example, drives using 150GB platters are sorted into the 160GB/platter section, and drives using 200GB platters are sorted into the 250GB/platter section.

The total capacity of the drive is shown beside each drive model.

A platter-head ratio is shown next to the total capacity tag in brackets. For example, a drive with a (1/2) ratio has one disk and two read/write heads. Drives that leave some amount of their platters unused in order to fit into a certain capacity (such as a 320GB drive based on a 500GB platter and two heads, which would have ~180GB space unusable) are marked as [short-stroked] next to the platter-head ratio accordingly.

Any special features (increased rotational speed, interface types, unusual platter designs and stuff like that) are noted where necessary.

Note: These drives, being designed for low power usage, automatically park their read/write heads when idle for a few seconds, much like laptop drives. For those who find this quirk annoying, here is a decent tutorial with instructions on how to turn the head parking off entirely.

250GB/platter Section (all drives under here use platters that can hold 250GB of data.)

What an unusual capacity this drive has. WD sold these as "lucky" drives in China because of the amount of 8s making up the capacity, though it seems some people (not necessarily in China) have also gotten the drives sent to them as replacements for RMA'd units of similar capacity.

500GB/platter Section (all drives under here use platters that can hold 500GB of data.)

Caviar Green (5400RPM, 8MB cache, SATA-300 interface)

WD3200AAVS-00N7B0 320GB (1/2 [short-stroked])

WD5000AAVS-00N7B0 500GB (1/2)

Caviar Green (5400RPM, 32MB cache, SATA-300 interface)

WD5000AADS-00S9B0/00L4B 500GB (1/2)

WD7500AADS-00M2B0 750GB (2/3)

WD10EADS-00M2B0/11M2B2/65M2B0 1TB (2/4)

WD15EADS-00P8B0 1.5TB (3/6)*

WD20EADS-00R6B0/14R6B0/00H7B0/00S2B0/00W4B0 2TB (4/8)

*Note: The WD15EADS may or may not actually use 500GB platters. I've heard reports of the drives running four 375GB platters, although that may have been a very early batch. (Edit: these 375GB/platter drives have the xxR6B0 code. Newer 3-platter variants have the 00P8B0 code.)

*I have noticed something a little odd with the 00J2GB0 revision of these two drives. They share the same quad-platter casing (hinting four platters inside), yet supposedly the WD15EARS uses one less platter, while both drives have near identical HD Tune results (from the screenshots that I have seen). I suppose WD just decided to use the quad-platter casing to house this three-platter drive, for some reason. The WD15EARS-xxZ5B1 models, in contrast, used the three-platter casing.

Caviar Green (5400RPM, SATA-600 interface, Advanced Format)

WD10EADX-00TDHB0/22TDHB0 1TB (32MB Cache) (2/4)

WD20EARX-00ZUDB0 2TB (64MB Cache) (4/8)

640-750GB/platter Section (all drives under here use platters that can hold 640-750GB of data.)

Caviar Green (5400RPM, 16MB cache, SATA-300 interface)

WD3200AACS-? 320GB (1/1)

WD20EACS-11BHUB0 2TB (3/6)*

*An oddball unit. Advanced Format is supported. It may or may not contain a trio of 667GB platters; if you have any information about this, please comment.

Caviar Green (5400RPM, 32MB cache, SATA-300 interface)

WD10EADS-00PAB0 1TB (2/3)

Note: Anyone out there want to submit an HD Tune screenshot of their WD10EADS-00PAB0? We'd like to see whether it is, in fact, just an Advanced Format-less version of the WD10EARX-00PASB0.

Note: Just like the new Seagate 2TB drives, two different platter configurations of the 2TB WD20EZRX appear to be floating around, with no easy way to tell the difference other than weight (640+ grams seems to signal three platters). Of course, the dual-platter version is the one to get.

WD30EZRX-00DC0B0/00D8PB0/00SPEB0 3TB (3/6)

Note: there's some confusion surrounding the WD30EZRX-00SPEB0. It uses WD's four-platter casing, unlike the other 1TB/platter WD30EZRX models, and looks physically identical to the WD40EZRX-xxSPEBx. It's either three 1TB platters, or four 750GB platters. Buyer beware!

WD40EZRX-00SPEB0/22SPEB0 4TB (4/8)

WD50EZRX-00MVLB1 5TB (5/10)

1.2TB/platter Section (all drives under here use platters that can hold 1.2TB of data each.)
